Glycine

Glycine (CAS 56-40-6), abbreviated Gly and designated E640, is the simplest amino acid and a high-volume industrial ingredient. It functions primarily as a pH buffer, humectant, and flavor modifier across pharmaceutical, food, and personal care manufacturing. In pharmaceutical manufacturing, this amino acid acts as a buffering agent in parenteral formulations and a stabilizer in lyophilized protein and vaccine products. Food producers use it as a flavor modifier and mild sweetness enhancer in seasonings and processed foods.

The ingredient is frequently utilized in beverages, where its regulatory designation supports EU-compliant labeling. In personal care formulations, it improves moisture retention in skin creams, serums, and hair care products, reducing the need for higher-cost humectants. It also serves as a key intermediate in the synthesis of active pharmaceutical ingredients, agrochemicals, and chelating agents such as glyphosate and EDTA derivatives. This versatility makes it a staple for chemical synthesis and industrial manufacturing.

The product is supplied as a white crystalline powder in bulk bags, drums, and fiber containers. Standard grades include USP, BP, Ph.Eur., and FCC, covering both pharmaceutical and food-grade procurement requirements. Technical grade is available for industrial synthesis applications where compendial certification is not required. Our supply chain ensures consistent quality and availability for large-scale operations across multiple global industrial sectors.
